Defatted Silkworm Pupa Powder
Why is silkworm pupa powder defatted?
Silkworm pupa powder is defatted to prevent the oxidation and rancidity of its abundant unsaturated fatty acids, avoid the production of harmful substances and extend the shelf life. Meanwhile, it increases the proportion of core nutrients such as protein to optimize utilization efficiency and improves the powder fluidity for convenient processing and mixing.

Feed Industry
Defatted silkworm pupa powder is a high-quality protein-rich feed ingredient with a balanced amino acid profile. It can replace fish powder and soybean powder, and is suitable for aquaculture, livestock, and special breeding. This product meets the growth requirements of aquatic animals, pigs, chickens and other livestock, and improves their growth rate, reproductive performance, and feed conversion rate.
Food Industry
After deodorization and sterilization, defatted silkworm pupa powder can be used as a nutritional fortifier. It is rich in proteins, minerals, and vitamins, and can be added to staple foods such as bread and noodles to increase protein content. It is also applicable for manufacturing high-protein meal replacement powders and nutrition bars to meet the protein needs of fitness enthusiasts.
Biological Products Industry
Defatted silkworm pupa powder serves as an excellent nitrogen source for microbial fermentation. It can promote the proliferation of strains (e.g., enzyme preparations and probiotics) and the synthesis of metabolites, thereby facilitating the optimization of fermentation processes.
High Protein & Amino Acid-Rich
The crude protein content of defatted silkworm pupa powder exceeds 65%. It is abundant in animal essential amino acids including lysine, methionine and tryptophan, with a ratio close to the ideal protein pattern.
Low Fat & Extended Shelf Life
With a fat content of ≤ 5%, defatted silkworm pupa powder is resistant to oxidative rancidity, which helps extend the shelf life of food and feed products. Meanwhile, it reduces cholesterol levels and prevents excessive fat deposition in human and animal bodies.
Palatability & Digestibility
Defatted silkworm pupa powder eliminates part of the fishy and greasy taste of raw silkworm pupae, resulting in a milder flavor profile. The defatting process modifies the macromolecular structure of proteins, breaking them down into small-molecule peptides and amino acids, thereby enhancing digestive absorption rate.
Q1: What are the functions of defatted silkworm pupa powder?
Defatted silkworm pupa powder is readily absorbable, ideal for nutritional supplementation. It also contains unsaturated fatty acids that regulate metabolism and boost immunity. It enhances the growth performance of farmed animals in feed applications, and acts as a nutritional fortifier in food and health products.
Q2: Is defatted silkworm pupa powder good for the body?
Defatted silkworm pupa powder is beneficial to human health. It retains the characteristics of high protein and low fat, and contains various amino acids, vitamins and other nutrients. It can supplement nutrition and facilitate muscle repair. In addition, it is rich in unsaturated fatty acids, which can help regulate blood lipids and enhance digestive and absorptive capacity.
Q3: What's the difference between defatted silkworm pupa powder and silkworm pupa powder?
The key is their fat and protein levels. silkworm pupa powder has around 20% fat and 50% protein-it's easy to oxidize, defatted silkworm pupa powder goes through degreasing, with 5% fat and 65% protein. It doesn't oxidize easily and stays good in storage.
